Splunk CVE-2024-45731: Potential Remote Command Execution (RCE) through arbitrary file write to Windows system root directory when Splunk Enterprise for Windows is installed on a separate disk

In Splunk Enterprise for Windows versions below 9.3.1, 9.2.3, and 9.1.6, a low-privileged user that does not hold the “admin” or “power” Splunk roles could write a file to the Windows system root directory, which has a default location in the Windows System32 folder, when Splunk Enterprise for Windows is installed on a separate drive. The user could potentially write a malicious DLL which, if loaded, could result in a remote execution of the code within that DLL.
